3 is a view for explaining a control method of the control device 240 for managing the user sleep environment in the smart home system 200 according to the first and second embodiments of the present invention.

According to the first embodiment of the present invention, when the user prepares the elevation, the control device 240 acquires the elevation preparation information through the sensor 210 or obtains the elevation preparation information by the user's input. Can be. After the user elevation preparation is confirmed, the control device 240 maintains the brightness of the at least one electronic device 250 at a predetermined relatively low value for a predetermined elevation preparation time, and after the elevation preparation setting time has elapsed. The lighting and / or display of the at least one electronic device 250 or the at least one electronic device 250 may be turned off.

Subsequently, when a predetermined wake-up call setup time arrives, the control device 240 may turn on the at least one electronic device 250 and control the brightness to a predetermined relatively high value.

That is, according to the first embodiment, the control device 240 may manage the sleep environment of the user according to the setting regardless of the state of the user during sleep.

According to the second embodiment of the present disclosure, when the user prepares the elevation, the control device 240 acquires the elevation preparation information through the sensor 210 or obtains the elevation preparation information by the user's input. Can be. The control device 240 may maintain the brightness of the at least one electronic device 250 at a predetermined relatively low value after the preparation of the user elevation is confirmed. The control device 240 may acquire the sleep phase of the user from the sensing data generated by the sensor 210 by sensing the user's state. For example, when the user enters the REM sleep stage from the awake stage after the preparation of the user's elevation, the control device 240 is controlled to the predetermined relatively low value brightness. The lighting and / or display of the at least one electronic device 250 or the at least one electronic device 250 may be turned off. This is because it is judged that the user has entered.

Then, when the user's REM sleep step immediately before the predetermined wake-up call setting time arrives, the electronic device 250 may turn on the at least one electronic device 250 and gradually increase the brightness. have. The brightness of the at least one electronic device 250 may be controlled to a predetermined relatively high value at the wake-up call setup time.

That is, according to the second embodiment, it is possible to manage the sleep environment adaptive to the user by using the sleep step of the user acquired based on the user state sensing data.

4 is a diagram illustrating a control method for managing a user's sleep environment in the smart home system 200 according to the third embodiment of the present invention.

According to the third embodiment, the control device 240 can manage the user sleep environment suitable for each section in the elevation control section P0, the weather control section P1, and the control section P2 during sleep.

The elevation control section P0 may include a section of time t1 until the user enters the first NREM sleep stage after the elevation time t0 after the preparation of the elevation of the user is confirmed. . The control method of the system in the elevation control section P0 will be described in detail with reference to FIG. 5A.

FIG. 5A is a flowchart illustrating a control method 510 of the smart home system 200 in the elevation control section P0.

In operation 511, the sensor 210 may sense a state of the user. For example, the sensor 210 may be activated at a set time, or may be activated at the moment of detecting the presence of a user. In order to acquire information related to whether to prepare for the initial user elevation, the sensor 210 may sense a user state that may determine the preparation for the user elevation. For example, the sensor 210 may acquire an image of a user (eg, an image of an in bed state). However, it is not limited to this.

In operation 512, the signal processor 220 may detect an elevation preparation of the user based on the sensing data of the sensor 210. In operation 513, the sensor 210 may sense a state of the user. The sensor 210 may perform the sensing of step 513 after receiving the signal indicating that the user prepares the elevation preparation from the signal processor 220, or may sense the user's state regardless of this. The sensor 210 may generate sensing data through sensing at least one of pressure, an image, vibration, and acceleration.

In operation 514, the signal processor 220 may process the sensing data to calculate sleep information of the user, for example, the user's sleep stage and / or elevation immersion. An example of the signal processor 220 processing the sensing data to obtain sleep information of a user is illustrated in FIG. 6.

In operation 515, the signal processor 220 may manage the database by accumulating the obtained sleep information and the sleep data in the database. The database may be updated and stored based on accumulated data, such as statistics, patterns, or time information of sleep data in each sleep stage.

In operation 516, the control device 240 may control the brightness or the wavelength (color of light) of the at least one electronic device 250 based on the sleep information. For example, when the preparation of the elevation of the user is detected, the control device 240 may gradually reduce the brightness of the at least one electronic device 250 below the maximum brightness (eg, 10 lux) based on the elevation of the user. You can.

In addition, when the preparation of the elevation of the user is detected, the control device 240 may adjust the output of the first wavelength band of the at least one electronic device 250 based on the elevation of the elevation of the user. For example, the control device 240 may gradually increase the blocking rate of the output of the first wavelength band within the maximum blocking rate based on the elevation of the user's elevation. The first wavelength band may include, for example, a blue wavelength. The blue wavelength is a short short wavelength and may be, for example, a wavelength based on 380 nm to 500 nm or 460 nm. An example in which the control device 240 controls the blocking rate of the first wavelength band output is shown in FIG. 8.

In operation 517, the control device 240 may detect that the user has entered the first non-remem sleep stage. In operation 518, the control device 240 may turn off the at least one electronic device 250 or turn off the illumination and / or display of the at least one electronic device 250.

5B is a flowchart for describing a control method 520 of the smart home system 200 in the weather control section P1.

In operation 521, the sensor 210 may sense a state of a user who is sleeping. The sensor 210 may generate sensing data through sensing at least one of pressure, an image, vibration, and acceleration.

In operation 522, the signal processor 220 may process the sensing data of the sensor 210 to determine a sleep stage of the user.

In operation 523, the control device 240 may inquire sleep data (eg, a preset wake-up time and / or sleep pattern of the user) stored in the database.

In operation 524, the control device 240 may determine whether the user enters the BERM sleep stage immediately before the weather, based on the inquired sleep data. For example, if the wake-up time is set in advance, the control device 240 may determine whether the user has entered the NREM sleep stage immediately before the set wake-up time. If the wake-up time is not preset or if the user wishes to base the wake-up time on the user, the control device 240 obtains sleep step information of the user obtained from the signal processor 220 from the database. The sleep pattern of the user may be matched to determine whether the user has entered the NREM sleep stage immediately before the expected wake-up time.

If it is determined that the user enters the sleep stage (NREM) sleep just before waking time, the control device 240 may control the brightness and / or the wavelength of the at least one electronic device 250 in step 525. For example, the control device 240 may increase the brightness of the at least one electronic device 250 step by step. If the output of the first wavelength band is partially blocked in the preceding control section (eg, the elevation control section P0), the control device 240 may reduce the blocking rate of the output of the first wavelength band. . The first wavelength band may include, for example, a blue wavelength.

In operation 526, the control device 240 may detect the user's wake based on the user's sleep stage.

If the user's weather is detected, the control device 240 may control the brightness and / or the wavelength of the at least one electronic device 250 in step 527. For example, when the user's weather is detected, the control device 240 may control the brightness of the at least one electronic device 250 to a maximum value for a preset time. This is to help the user wake up after the weather. In addition, when the user's weather is detected, the control device 240 may control the output of the first wavelength band of the at least one electronic device 250 to be exaggerated than the normal value for the preset time.

In operation 528, the control device 240 may determine whether the preset time has elapsed. That is, the control device 240 may determine whether the awakening time has arrived after the preset time elapses.

If it is determined that the awakening time has arrived, the control device 240, in step 529, at least one electronic device 250 that causes the output of the brightness and the wavelength to be exaggerated, returns the brightness and the first wavelength band to a normal state. You can control the output.

5C is a flowchart for describing a control method 530 of the smart home system 200 in the control period P2 during sleep.

If the control device 240 determines in step 524, the user may not have entered the NREM sleep stage just before waking time. In this case, the control device 240 may detect whether the user has an abnormal weather in step 531. For example, the rate of REM sleep is high during normal time, as in normal weather, the person does not enter a deep sleep phase for about 2 hours before waking up. Therefore, the control apparatus 240 can determine the abnormal weather condition for the other weather conditions.

If it is determined that the user has abnormal weather, the control device 240 may control the brightness and / or the wavelength of the at least one electronic device 250 in step 532. For example, the control device 240 may gradually increase or decrease the brightness of the at least one electronic device 250 within a limited value (for example, 10 lux). In addition, the control device 240 may exaggerate and partially output the second wavelength band output. The second wavelength band may include, for example, a dark red wavelength. In addition, the control device 240 may output the first wavelength band (eg, blue wavelength) by partially blocking (removing) the output.

In operation 533, the control device 240 may detect whether there is an additional movement of the user. If the additional motion is detected, the control device 240 may increase the brightness of the at least one electronic device 250 step by step or more in step 534.

If the user sleeps while maintaining the in bed state, the system may again perform the control method 510 of the control section P0 during the elevation.

6 is a diagram illustrating an example of how the signal processor 220 calculates sleep information from sensing data.

Referring to FIG. 6, for example, the signal processor 220 processes the sensing data first, as in 605, to obtain meaningful data (eg, breathing, movement, heart rate variability, or heart rate) required to obtain sleep related information of a user. Can be generated. At this time, the pattern of sensing data matched based on the data pattern defined in the database may be detected to detect breathing, movement, heart rate variability or heart rate. For example, when the sensing data is an image input, the movement of the user may be detected by moving the pixel with the previous frame. In addition, the signal processor 220 may obtain information related to the sleep stage of the user from the sensing data. The signal processor 220 may detect a sleep stage of the user by finding a pattern of sensing data that matches the data pattern defined in the database. The user's sleep stage, movement, breathing, heart rate variability, and heart rate are present as individual values, but since there is a causal relationship with each other, induction of other data from at least one data is possible.

The signal processor 220 may second process the first processed data as shown in 610. The signal processor 220 may calculate a data change, a stabilization speed, and / or a range of values of the first processed data (eg, breathing, movement, heart rate, or heart rate).

For example, when the input sensing data is referred to as d, the data change, stabilization speed, and / or range of values of the first processed data may be obtained as follows.

Data change: Δx (= xt-xt-1, closer to zero, closer to zero)

Stabilization rate: ∫ △△ x dx (≒ △ x, the closer to sleep the closer to zero.)

Range of values: Range of x (e.g. respiration rate ~ 30)

The signal processor 220 may have an internal or external sleep data database as shown in 615. The signal processor 220 may divide the sleep stage based on a predefined value, and the threshold value may be determined by comparing the sensing data, the processed data and the sleep stage. (E.g., respiratory rate 30, Δx = 1, ∫ΔΔx dx = 1) at the time of entering the NREM stage, such data may be accumulated and stored in the database, and may be stored as a sleep pattern or a statistical value. The signal processor 220 analyzes the sleep patterns or statistics stored in the database, such as 620, and the movement, breathing, heart rate variability, or heart rate from the awake phase to the REM sleep phase. Analyze data changes, stabilization rates, and / or ranges of values in relation to

The signal processor 220 may move, breathe, and heart rate during awake phase, first REM sleep stage, and first non-REM sleep stage stored in the database as shown in 625. Match the data associated with the variation in data, the rate of stabilization and / or the range of values in relation to the variability or heart rate with the processed data. In this case, the signal processor 220 finds an approximation value of the processed data among the statistical values stored in the database and sets the reference value based on the estimated value. It can be calculated by changing the time domain to the matching point in time.

The signal processor 220 may calculate an elevation of a user's elevation based on the matching as shown in 630. For example, the signal processor 220 may determine or predict the remaining time from the matched data until the entry into the NREM step, and immerse the user with ((current time-reference time) / remaining time until entering the NREM step). The degree can be calculated.

FIG. 7 is a diagram for describing a method of controlling the brightness of at least one electronic device 250 by the control device 240 in an elevation control section P0 and a weather control section P3.

The control device 240 may gradually decrease the brightness of the at least one electronic device 250 from the time point t0 when the preparation of the elevation of the user is detected. The control device 240 turns off the at least one electronic device 250 or illuminates the at least one electronic device 250 when a user enters a first NREM sleep stage. Alternatively, the display can be turned off.

Then, when the control device 240 detects that the user enters the REM sleep stage immediately before the wake-up time t3, the brightness of the at least one electronic device 250 is gradually increased from the time t2. It may be controlled to have a maximum value at the wake-up time t3. The controller 240 maintains the brightness of the at least one electronic device 250 at a maximum value for a predetermined time, and then controls the brightness to a normal value at a time t4 after the predetermined time has elapsed. have.

FIG. 8 is a diagram for describing a method in which the control device 240 controls the blocking rate of the output of the first wavelength band of the at least one electronic device 250 in the elevation control period P0.

Referring to FIG. 8, in operation 800, the control device 240 may preset a maximum blocking rate of the output of the first wavelength band of the at least one electronic device 250. The maximum blocking rate may be set according to the maximum blocking rate supported by the system. In operation 805, the control device 240 may check the elevation of the user. The control device 240 may increase the blocking rate based on the identified elevation immersion in step 810. The control device 240 may increase the blocking rate without changing the elevation immersion rate.

The control device 240 may check whether the blocking rate is the set maximum blocking rate in step 815. When the blocking rate is the set maximum blocking rate, the control device 240 turns off the at least one electronic device 250 when the user enters the first NREM sleep step without further control. The lighting or display of the at least one electronic device 250 may be turned off.

If the blocking rate does not reach the set maximum blocking rate in step 820, the control device 240 may detect whether there is an abnormal movement of the user. If the abnormal movement of the user is not detected, the control device 240 may continuously increase the blocking rate. On the other hand, if an abnormal movement of the user is detected, the control device 240 may fix or reduce the blocking rate in step 825.

In operation 830, the control device 240 may accumulate and store an elevation immersion level and a blocking rate of the user acquired as a result of performing the operation 815 or the operation 825 in a database. In addition, the control device 240 may calculate the data accumulated in the database as a blocking rate according to the sleep immersion rate in the next elevation process of the user.
